Optical disk drive

ABSTRACT

An optical disk drive includes a main body and a tray. The main body includes a housing, a first resisting member, and two rails. The first resisting member and the two rails are disposed in the housing. The tray is slidably coupled to the two rails, and is operable to be switched between a first state and a second state. The tray is received in the housing in the first state, and protrudes out of the housing in the second state. The tray includes a second resisting member, which is capable of being elastically compressed along a resisting direction substantially perpendicular to a sliding direction of the tray. The second resisting member is resisted by the first resisting member along the resisting direction to secure the tray in the first state. The second resisting member is away from the first resisting member in the second state.

BACKGROUND

1. Technical Field

The present disclosure relates to optical pick-up devices, andparticularly to an optical disk drive capable of tightly securing atray.

2. Description of Related Art

An optical disk drive usually includes a main body and a tray slidablycoupled to the main body. The main body includes two rails for allowingthe tray to slide therein. To decrease resistance between the tray andthe rails when the tray is sliding in or out, the tray is usually spaceda distance away from the rails. Thus, when the optical disk drive readsor writes to a spinning optical disk, the vibration of the tray causedby the play between the tray and the rails may lead to erroneous databeing read from or written to the disk.

Therefore, it is desirable to provide an optical disk drive capable oftightly securing a tray, which can overcome the above-mentionedproblems.

DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detailwith reference to the drawings.

Referring to FIGS. 1 and 2, an optical disk drive (ODD) 100 inaccordance with an exemplary embodiment is illustrated. In theembodiment, the optical disk drive 100 may be a slim type version,particularly employed in a laptop computer (not shown). The ODD 100includes a main body 10 and a tray 20 slidably coupled to the main body10. The tray 20 is adapted to receive an optical disk (not shown). Whenthe tray 20 is completely received in the main body 10, the disk drive100 is operable to drive the optical disk.

The main body 10 includes a housing 11, a first rail 13, and a secondrail 14. The housing 11 includes a bottom plate 114 and three sidewalls115, 116, 117 extending upright from three edges of the bottom plate 114respectively. The sidewall 115 is substantially parallel to the sidewall116. The sidewall 117 is substantially perpendicularly connected betweenthe sidewalls 115 and 116. The housing 11 defines a receiving space 118bounded by the sidewalls 115, 116 and 117. The first rail 13 and thesecond rail 14 are slidably disposed in the housing 11 and connected tothe sidewalls 115, 116 respectively. The first rail 13 is substantiallyparallel to the second rail 14. The first rail 13 and the second rail 14are operable to slide along a first direction D1 to be completelyreceived in the housing 11 and along a second direction D2 to partiallyprotrude out of the housing 11. The first direction D1 is opposite tothe second direction D2.

The second rail 14 includes a first resisting member 141 formed on oneend of the second rail 14 adjacent to the sidewall 117. The firstresisting member 141 includes a resisting surface 145 and a guidingsurface 143 (shown in FIG. 4). The resisting surface 145 is positionedaway from the sidewall 116 and substantially parallel to the firstdirection D1. The guiding surface 143 is connected to one end of theresisting surface 145 away from the sidewall 117. The guiding surface143 is inclined with respect to the resisting surface 145, and forms anacute angle with the second direction D2.

The tray 20 includes two opposite side surfaces 21 and 22. The sidesurfaces 21 and 22 face the first rail 13 and the second rail 14respectively. The tray 20 further includes two elongated slide bars 24formed on the side surfaces 21 and 22 respectively. The slide bars 24are substantially parallel to the first rail 13 and the second rail 14.The slide bars 24 are slidably connected to the first rail 13 and thesecond rail 14 respectively, such that the tray 20 is slidable withrespect to the main body 10.

Referring to FIG. 3, the tray 20 defines a concave space 221 in the sidesurface 22 adjacent to one end of the tray 20 towards the sidewall 117of the housing 11. The tray 20 includes a second resisting member 26suspended in the space 221. The second resisting member 26 includes acantilever beam 261, a spring portion 262, and a resisting portion 263.

One end of the cantilever beam 261 is fixed to the tray 20, such thatthe cantilever beam 261 extends into and is suspended in the space 221.The cantilever beam 261 is substantially parallel to the slide bar 24,and is elastically deformable towards the space 221. The spring portion262 is a winding sheet connected to a distal end of the cantilever beam261. In this embodiment, the spring portion 262 includes a first spacingportion 264, a second spacing portion 265, a first beam 266, and asecond beam 267. The first spacing portion 264 extends upright from thedistal end of the cantilever beam 261. The first beam 266 connects tothe first spacing portion 264 and is suspended over the cantilever beam261. The second spacing portion 265 extends upright from one end of thefirst beam 266 away from the first spacing portion 264. The second beam267 connects to the second spacing portion 265 and is suspended over thefirst beam 266. The first beam 266 and the second beam 267 aresubstantially parallel to and deformable toward the cantilever beam 261.As such, the spring portion 262 can be elastically compressed. Theresisting portion 263 is connected to a distal end of the second beam267 away from the cantilever beam 261 and protrudes out of the space221.

When the tray 20 slides along the first direction D1 (FIG. 4) to bereceived in the housing 11, the guiding surface 143 is adapted to guidethe resisting portion 263 to the resisting surface 145. When the tray 20is completely received in the housing 11 (the first state), theresisting portion 263 is pressed by the resisting surface 145, thus thespring portion 262 is compressed and the cantilever beam 261 iselastically deformed towards the space 221 accordingly. Therefore, thefirst resisting member 141 applies a resisting force to the secondresisting member 26 so as to tightly secure the tray 20. The directionD3 of the resisting force is substantially perpendicular to the firstdirection D1 and the second direction D2. Thereby, vibration of the tray20 during use can be decreased due to the resisting force.

Referring to FIGS. 5 and 6, when the tray 20 slides a predetermineddistance along the second direction D2 to be in the second state, thesecond resisting member 26 departs from the first resisting member 141and is spaced a distance away from the second rail 14. As such, aresistance to movement of the tray 20 is decreased.

In other embodiments, the second resisting member 26 can be disposed onthe main body 10, and the first resisting member 141 can be disposed onthe tray 20 correspondingly. Alternatively, two second resisting members26 can be mounted on both the side surfaces 21 and 22. Correspondingly,the first resisting members 141 can be mounted on both the first rail 13and the second rail 14.

Additionally, the first rail 13 and the second rail 14 do notnecessarily need to be slidable with respect to the housing 11.Alternatively, the first rail 13 and the second rail 14 can be fixed tothe housing 11.

Furthermore, the cantilever beam 261 can be omitted in otherembodiments. Correspondingly, the spring portion 262 is fixed to thetray 20.
